Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.Embodiment 1: the tower European type cooker hood that a kind of two-chamber air intake of the present embodiment 1 independently controls, as depicted in figs. 1 and 2, comprise main frame 1 and exhaust fume collecting hood 2, turbofan and controller is provided with in main frame, exhaust fume collecting hood is left and right double cavity structure, strut rail 21 is designed with between two-chamber, strut rail is provided with lubricating cup, be provided with in two-chamber can cover exhaust fume collecting hood air inlet and can open and close controlling web plate combination 3, web plate combination is high outside and low outside skewed along exhaust fume collecting hood left and right directions, web plate combination encloses with the sidewall of exhaust fume collecting hood the oil smoke absorbing chamber 22 forming taper, as shown in Figure 3, web plate combination comprises interior web plate 31 superimposed successively from top to bottom, the pulling mechanism 4 of movable screen 32 and outer web plate 33 and the movement of dragging movable screen, interior web plate is embedded and forms hollow chamber with outer web plate is fixing in web plate outside, movable screen to be arranged in this hollow chamber and slidably, four support spring sheets 34 are installed between movable screen lower surface and outer web plate upper surface, support spring sheet arcuately, the two ends bow pin of support spring sheet is supported on the upper surface of outer web plate, and the bow top of support spring sheet is posted by the lower surface of movable screen, the lower surface that movable screen is leaned at interior web plate by the support of support spring sheet, interior web plate is designed with the position block 35 matched with support spring sheet, can be used for the displacement of geocoded activity web plate, interior web plate and movable screen are all processed with the even and equal-sized strip hole 311 in interval, strip hole on interior web plate is with the strip hole one_to_one corresponding on movable screen and the formation wind inlet channel that communicates, the strip hole edge of interior web plate protrudes from interior web plate upper surface, between the sidewall of neighboring strips hole, plate face forms the Oil Guide passage 312 of indent, outer web plate is also processed with the slotted eye 331 that interval is even and consistent with the strip hole direction on interior web plate, slotted eye edge protrudes from outer web plate upper surface, plate face between adjacent slot sidewall also forms the Oil Guide passage of indent, oil smoke first enters hollow chamber through outer net board slot hole, sucked by turbofan by the strip hole of movable screen and interior web plate again, the upper surface of web plate is provided with filter screen for improving filtering oil smoke ability outside, the pulling mechanism of movable screen comprises the motor 41 with reducing gear, drag-line 42 and the line wheel 43 be set on motor output shaft, motor is arranged on the edge, side of interior web plate, interior web plate has guide-localization hole 313 near the side surface design of motor, the transverse holes in guide-localization hole is apart from equal with a half-distance of neighboring strips pitch of holes on interior web plate, the position in corresponding guide-localization hole, movable screen surface is mounted with the vertical inserted sheet 37 matched with guide-localization hole, vertical inserted sheet inserts also can along guide-localization hole transverse shifting in guide-localization hole, one end of drag-line is connected with the top of vertical inserted sheet, the other end is wound on line wheel, movable screen is provided with Compress Spring 38 near the side of motor, Compress Spring one end and interior web plate sidewall are fixed, the other end connects with movable screen, movable screen overcomes Compress Spring active force and transverse shifting by pulling mechanism, the distance of transverse shifting be guide-localization hole hole in distance, the opening and closing that web plate combines inlet air door can be controlled by the relative position change of interior web plate and movable screen.
When range hood uses, for the service condition of kitchen range, when only only having a burner job, just the air inlet of this burner is opened, the air inlet of opposite side then needs to close, now, the electric motor starting in the web plate combination of air inlet need be closed, line wheel on drive motor output shaft rotates, drag-line on line wheel overcomes the active force of Compress Spring by vertical inserted sheet dragging movable screen and slides, because vertical inserted sheet can only move along guide-localization hole, make movable screen can only the distance of interior pitch-row in transverse shifting guide-localization hole, therefore the strip hole offset distance on movable screen is a half-distance of neighboring strips pitch of holes, as shown in Figure 4, strip hole mutual dislocation on strip hole on movable screen and interior web plate, strip hole on the movable screen originally communicated with the strip hole on interior web plate is tightly covered by the plate face on interior web plate, the air door completing web plate combination is closed, the oil smoke absorbing chamber of this side cannot air draught, the suction air volume of turbofan collects in use side completely, the suction air volume of this side increases and is sucked completely in exhaust fume collecting hood by the oil smoke that kitchen range are discharged, opposite side then not air draught, with strong points and energy-conservation, and can prevent from being mixed into other air and reducing fume-exhausting efficiency, the web plate combination of tilting also is conducive to the collection of oil smoke drop, flow in strut rail in many Oil Guide passages that the oil smoke drop fallen through movable screen and the cohesion of Intranet plate resistance gear can be collected on interior web plate or outer web plate, collect finally by lubricating cup, make exhaust fume collecting hood inner surface and main frame cleaning inside health.
When two burners as kitchen range all work, now, the side that shutter is closed need reopen, then can reversely rotate and be with moving-wire wheel also to rotate backward by starter motor, drag-line unclamps, movable screen resets under the effect of Compress Spring, as shown in Figure 5, strip hole on movable screen is aimed at again with the strip hole on interior web plate and is communicated, air door reopens, and two oil smoke absorbing chamber air doors of exhaust fume collecting hood are all opened, and realizes both sides air draught simultaneously, suction air volume uniform balance and not easily suck other cleaned airs, fume-exhausting efficiency is high.
Embodiment 2: the tower European type cooker hood that a kind of two-chamber air intake of the present embodiment 2 independently controls, comprise main frame and exhaust fume collecting hood, as shown in Figure 6, the grease baffle parallel with slotted eye is also designed with above many slotted eyes of web plate outside, the lateral cross section of grease baffle is curved, the projection line of grease baffle both sides of the edge all drops in corresponding Oil Guide passage, the grease baffle of larger area can stop the oil smoke that interception sucks, the oil droplet of cohesion can glide along grease baffle, and from the landing of grease baffle edge to Oil Guide passage in and conflux to strut rail, collect finally by lubricating cup, can prevent oil droplet from dropping on the kitchen range top from the slotted eye of outer web plate, also the sanitation and hygiene of exhaust fume collecting hood inner surface and main frame inside are made, the other parts of the present embodiment 2 all with the appropriate section of embodiment 1 roughly the same, repeat no more herein.
In describing the invention; technical term " on ", D score, "front", "rear", "left", "right", " interior ", " outward " etc. represent that direction or position relationship are based on direction shown in the drawings or position relationship; be only for convenience of description with understanding technical scheme of the present invention; more than illustrate and not restriction has been done to the present invention; the present invention is also not limited only to the citing of above-mentioned explanation; the change that those skilled in the art make in essential scope of the present invention, retrofit, increase or replace, all should be considered as protection scope of the present invention.
